6. Integration with SPECTRE Profiler

D3-TUI will integrate with SPECTRE’s profiler (Spec 8):

/* Initialize profiling */
void d3tui_profiler_init(void) {
    sh_prof_init(&profiler, PMCR_OPERAND_CACHE_READ_MISS_MODE);

    // Register zones
    zone_terminal = sh_prof_zone_register(&profiler, "terminal");
    zone_render = sh_prof_zone_register(&profiler, "render");
    zone_input = sh_prof_zone_register(&profiler, "input");
    zone_vmu = sh_prof_zone_register(&profiler, "vmu");
}

/* Profile a function */
void d3tui_term_update(d3tui_terminal_t *term) {
    sh_prof_zone_begin(&profiler, zone_terminal);

    // Terminal update code
    // ...

    sh_prof_zone_end(&profiler, zone_terminal);
}

/* Get profiling stats */
void d3tui_profiler_print_stats(void) {
    sh_prof_print(&profiler);
}

/* Dump profiling data */
void d3tui_profiler_dump(const char *path) {
    sh_prof_dump(&profiler, path);
}
